EMERGENCY TIRE FOR VEHICLES Application filed June 7,

This invention relates to an emergency tire for vehicles, the object of the invention being to provide a tire which can be quicklyr and easily placed in position over a deiiated or flat tire thus taking the weight of the vehicle oli the latter so that the vehicle may continue on its way without injury to the deflated tire. I i

A further object of the invention is to provide a tire of this character which is separable into a plurality of segments whereby it can be stored in a comparatively small space.

YWith the foregoing and other objects 1n view, which will appear as the description proceeds, the invention consists in the novel features of construction and combination of parts which will be more fully described hereinafter and particularly pointed out in the 2 0 claim. l

In the drawings accompanying and forming part of this specification, Y

The same characters of reference designate the same parts in the different figures of the drawings.

Referring to the drawings, 1 designates 4&0 the hub of a wheel, 2 the spokes, and 3 the elly, the usual metal rim being designated 4 and the shoe or casing 5 in which isv carried the iniiated inner tube, not shown. Only a conventional form of wheel is shown, it

the subject-matter of the present invention is capable of use in connection with the wheels oi' any motor vehicle. i i

The emergency tire comprises a plurality of metallic arc-shaped members or segments 6 adapted to orm',whenassembled, a com-` plete rim, each of said ysegments havingy secured to its outer periphery asimilar segf ment of solid rubber 7.' In the present instance the rimis shown as ma'cleup of four such members, but 'it will be obvious that it may be divided into six vor my (Other. suit-- able number depending on the particular` wheel with which it is to be used. ln practicethe seofements are halved7 at their ends in such manner that adjacent segments over# lap at their-,ends thereby properly to break joints as shown in Fig. l. For securing the device to the vehicle wheel, each of the metal segments is provided approximately at the center of its length with avlug 8 extend` ing' radially therefrom, towardv the axisuof .rotation of' the wheel, each of'said lugs'being provided with a perforation for the pas'- sage ofone of the usual rim bolts 9.0f the wheel, it being understood that the, peri-ora-y tions of the lugs are sufliciently far fronr. the metal segments so that when ,theI lugs are bolted to the telly 3, the metal segments are maintained at such a distance Jfrom the rim 4 of the wheel as to aecommodatea nat or partly deiiated tire between said rim and metal segments so that when the device is in use none of the weight of the vehicle will be borne bythe deiiated tire. y In order to afford further rigidity to the segments 6 and prevent them from pivoting on the bolts 9, I have provided stays in thev form of tie rods connecting the metal seg,- ments 6 with the hub ofthe Wheel. Each olf f thesegments hassecured near one end thereof one member or `lialtml() of a tie rod, the other1 half' l0a ffwhch isy Secure-,film O11@ heli cia hinged split ring l1, the opposing eppq.

j thereto.

10a being engaged by an interiorly threaded sleeve l2 as in any well known tie rod. If desired, a transverse pin 13 may be secured in each of the sleeves 12 for rotating the sleeve, or the pin may be omitted and the sleeve merely provided with a transversely extending perforation approximately at the center of its length for the reception of a tool. The halves of the ring 11 are hinged together at 14, one of said halves being provided at its free end with a threaded pin 15 and a wing nut 16, while the other is provided with a bifurcated member 17 adapted to straddle said pin when the halves are swung together.

It is believed that the operation of the device will be clear from the foregoing.

Upon the discovery of a flat tire, the driver of the vehicle will first clamp the ring 11 to the hub of the wheel. the nut from one of the rim bolts and place one of the segments 6 of the emergency tire over the flat tire with the perforation in its lug 8 in position to receive the bolt, and the nut replaced. An eXtra long set of rim bolts may be provided for this purpose. The portion l() and 10a of the tie rod are then coupled together inthe sleeve 12 and adjusted to the required length. The next two segments are applied in the same manner and the car is then moved suiiiciently to cause that portion of the flat tire which Was in contact with the road when the ear stopped, to move up into position to have the last segment applied The vehicle can then continue on its waywithout danger of damaging the flat tire. After it has accomplished its purpose the emergency tire can be removed and stored in a comparatively small space in the car. It is frequently inconvenientand sometimes impossible to repair a flat tire on the road, and as often happens, if there is no spare tire it becomes necessary either to wait until help can be obtained or to drive on the fiat tire, which of course is very injurious to the tire. Moreover, even though the vehicle may be equipped with a spare tire, if the driver is a woman the changing of a tire-is too great a taX on her strength and many Would prefer ,to run on the flat tire, even at the risk of ruining it, than either to attempt to change it or to wait for assistance.V The present invention is intended to meet this situation and to furnish a device which can be quickly and easily vapplied by a woman and which will permit the vehicle to continue'on its way without the necessity of removing the flat tire and without risk of injuring the latter.

Having thus described my invention, what I claim is:

The combination with a vehicle wheel, of an emergency tire comprising a plurality of segments, a lug carried by each of said segments approximately midway of its length,

said lug extending radially from the inner He will then remove CHARLES GERBEN.
